    Default slow ssd's

    slow ssd's-840-evo256-06-march-2015_05-18-pngI have 2 ssd's in my system. and decided to run hd pro on them and am very disappointed with the speed. One the 840 evo 250Gb its only reading average 305mbs 335mbs was the top speed. My os is on that and i did upgrade the firmware. The other is an m4-256GB.
    Its max read was 293mbs and average 276mbs. I used hd tune pro 5.50. Bios are set yo ahci so what could be the problem. My specs are below. I posted here since its an asrock extream 6 board.

    Check your motherboard user manual to make sure that each of the ssd's data cables are connected to the Intel sata3 ports.

    The ASMedia sata3 port performance is inferior to the Intel sata3 ports for ssd's.

    A much better ssd benchmark is Anvil's Storage Utilities Download Version 1.1 2014

    The 4K small file performance is much more important than the large sequential read/write results.

    Include an AS_SSD benchmark for each ssd so that we can see if the partition alignment is properly set on a 4K boundary.

    The benchmark results below are with my P35 system using the native Intel sata2 ports.

    Reread post #2 to make sure that your ssd''s are connected to the Intel sata3 ports!!

    Without the proper 840 Evo firmware update, its performance is degraded in some circumstances.

    As Prof Jim said, the ASMedia SATA ports that are supposed to be SATA III, really are not fully SATA III. Your sequential read speed of ~300MB/s clearly shows that you have the EVO connected to an ASMedia SATA port.

    The ASMedia SATA chipset is only able to be connected to one PCIe 2.0 lane at 5Gb/s, not the full 6Gb/s of SATA III. SSD enthusiasts know that the ASMedia and most of the Marvell add on "SATA III" chipsets do not perform as well as the Intel SATA III chipsets.

    The four SATA ports at the top of the stack of ten SATA ports on your board are connected to the two ASMedia SATA chipsets on this board. All you need to do is move the SATA data cable of your EVO to one of the six Intel SATA III ports below the four ASMedia SATA ports. Check the manual to find the Intel SATA ports.

    Well you where right that i didn.t have it connected to the Intel chipset. So ive put it in the one asrock suggest for boot drive. Down loaded Anvil's benchmark.
    Heres my results. Why are they so different in some spots then your's.slow ssd's-samsung-ssd-840-evo-250g-scsi-disk-device_250gb_1gb-20150306-1555-png

    Well ProfJim use 840 Pro on Sata2 port, you use 840 EVO on Sata3 port. Big differences are expected.
